Application filed April 17, 1924. Serial No. 707,272.

To all whom it may concern:

Be it known that I, JOHN H. MoCLnL- LAND, a citizen of the UnitedStates, residing at Forestville, in the county of Hartford and State ofConnecticut, have invented a new and useful Improvement in WashingMachines, of which the following is a specification.

This invention relates to the type of wash ing machines designed tobeplaced in a household boiler in which clothes and similar articles areto be laundered.

The object of the invention is to provide a simple, cheap, portableapparatus which when placed in a wash boiler and the water therein isboiled will automatically cause jets of hot water and soap or othercleaning substance to be forcibly directed upon the articles beingwashed in such manner that they will be more thoroughly cleaned than ifmerely boiled.

This object is attained by forming channels in the under side of asupporting base and connecting these channels with a tubular uprightthat has nozzles which extend outward and terminate in downward andbackward openings or mouths. The channels in the under side of the baseare of such shape that when the device is set upon the bottom inside ofa boiler placed on a stove or gas heater, the heat which arises from thecombustion of the fuel beneath the boiler, transforms the water in thechannels into steam or vapor, the pressure of which is such as to causean upfiow of steam and hot water through the vertical tube and outthrough the horizontal nozzles. The force of this flow causes a strongcirculation of the cleansing liquid and the nozzles project it downwardonto the clothing or other articles being washed with sufiicient powerto more or less agitate the articles, which particularly when taken inconnection with the agitation incident to the general boiling of themass of clothing causes the water to drive through ordinary material andthus effect a thorough cleaning.

In the accompanying drawings Fig. 1 shows a plan of the device. Fig. 2shows a side elevation with the lower portion of the upright and thebase cut in section. Fig. 3 shows a bottom view of the base. Fig. 4shows a side view of the lower portion of the device.

The base 1 of the device illustrated is circular, although it may be ofother shape if desired, and it is made of brass or other metal suitablyplated to prevent corrosion. The base is of such weight that the devicewill not become upset when in use. 'llhrough the center of the base is aperforation in which the lower end of an upright tube 2 is fastened. Thebottom of the tube does not reach to the under surface of the base inorder to leave a central'recess 3 that communicates with the opening inthe tube. At the top of the upright tube are two horizontally extendingnozzles 4 the outer ends of which are curved oppositely and down wardlyso as to discharge whatever liquid is forced through them obliquely withrelation to the axis of the upright and also to the plane of the base.

In the bottom of the base are two tapering channels 5. These channelscurve from the periphery of the base to the central recess and they aremuch wider at their outer ends than where they open to the centralrecess. The inner ends of these channels point to the opening at thelower end of the upright tube and on account of being restricted,pressure which is generated in the central recess tends to escapethrough the upright tube and nozzles rather than back through thechannels.

It is desirable to form in the bottom of the base two channels 6 thatextend outward from the central recess to openings in which the lowerends of two pressure stabilizing chambers 7 are fastened.

In use when the heat under the boiler becomes sufficient the water inthe central recess and channels becomes converted into steam and thesteam escapes upward through the vertical tube and out through thenozzles, carrying more or less of the cleaning liquid with it. Owing tothe restricted orifices of the intake channels the pressure generateddoes not drive the water back out of the channels but carries it upwardcausing a rapid circulation. When the chambers are provided the pressureof the steam is stabilized so that the outflow of steam and waterthrough the nozzles is substantially steady.

The invention claimed is A washing machine comprising a heavy basehaving in its lower face a central circus lar recess, uniformly taperingintake channels in the bottom face of said base, said channels curvingfrom the periphery to the central recess with Which they communicateWith restricted orifices, and channels in the bottom face of the baseleading transversely outward from the central recess, equalizingchambers above the base and communicating with the outer ends of thelatter channels, an upright tube communicating With the ;-hannel recess,and nozzles extending oppositely outward and curved downward from thetop of said tube.
